If not all mutations that contribute to species evolution are passed down, what conditions must be met for a mutant trait to be inherited by the next generation?
If you were comparing the karyotypes of species that are closely related evolutionarily, what types of similarities and differences would you expect to find?
Even though they have several differences, a bacterium and a human cell will both contain DNA. With respect to evolution, what does this fact suggest?
